The sink is a Home Depot two tub model. I bolted it to the rolling base constructed out of angle iron & diamond plate. Water connections from the house are basic ball valve out of the wall that stub into whashing maching 10' hoses
They connect to the sink
I core drilled a hole through the foundation of the garage wall. There is crawl space under the house adjacent to the garage wall.
I ran a 3" drain line up to the foundation wall. Then using the rubber reduction fitting above ran a 10' long piece of 2" into the 3" main drain.
I left the hose clamp on the 2" rubber reducer loose so that the 2" line slides in & out of the 3" line.
Add a little lubricant and it works great!
